Answer:
Step-by-step explanation:
Parallel lines are lines that never meet, from the question in the attachment above, the two lines that cannot meet are lines 'a' and 'b' and lines 'c' and 'd'
4. Question four is then lines b and a which is option B
Perpendicular lines are lines in which the angle between them is right angle (90 degrees). Which are 'a' and 'c', 'a' and 'd', 'b' and 'c', 'b' and 'd'
5. Question 5 is therefore 'a' and 'c' which is option D
Answer:56.52
Step-by-step explanation:2x3.14=6.28

18.84x3=56.52
Let 
be the number of liters of the 10% solution she needs to use. She'd end up with a 6% solution with a volume of 
liters. The starting solution contains 0.04*9 = 0.36 liter of salt. Each liter of the 10% solution contributes 0.1 liter of salt, so that
Solve for :
so Mayra needs to add 4.5 liters of the 10% solution.
Answer:
B. 0.72
Step-by-step explanation:
In order to find the answer we need to use the following formula:
where:
